Application filed November 9, 1912. Serial No. 730,416.

To all whom. it may concern.

Be it known that I, AUoUs'r RmNIiNunu, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and usefulv Improvements in AdjustableMolding-Stamp Racks, Of which the following is a specification.

This invention relates to a mohling stamp rack.

It is the object of this invention to provide a rack for molding orrubber stamps, which is adjustable to adapt it to hold stamps of variouswidths.

Another object is to provide a stamp rack which is simple inconstruction, durable and inexpensive to manufacture.

Other objects will appear hereinafter.

The invention primarily resides in a supporting plate having upturnedflanges on its sides and ends, serrations or teeth on the inner tacos ofthe end flanges, and a series of removable partition bars adapted tohave their ends inserted in the interstices between the teeth on the endflanges to divide the bearing plate into aseries of compartments.

The invention further consists ot the parts and the construction andcombination of parts as hereinafter more fully described and claimed,having reference to the accompanying drawings, in which- Figure 1 is afront elevation of the invention. Fig. 9. is a view in vertical. sectionon the line XX of Fig. 1. Fig. 3 is a detail in perspective of the endportion of the partition bar. Fig. .l.- is a detail section on the lineYY of Fig. 2.

In the drawings A represents a plate having upturned side and endflanges 2 and 3, respectively. Mounted on the inner faces of the endflanges 3 are corrugated plates t, forming serrations or teeth on theinner faces of the end flanges. The space inclosed by the side and endflanges 2 and 3 is designed to be divided into a series of compartmentsfor the reception of molding stamps, for which purpose a series ofpartition bars 5 is provided. The bars 5 are preferably stamped fromsheet metal and are U-shaped in cross section. The bars 5 are of suchlength as to extend the length of the supporting plate A and have theirends converged to adapt them being inserted between the corrugations onthe inner faces of the end flanges 3, as shown in Fig. l. The convergentend portions of the bars 5 are ol such size and shape as tosubstantinlly fill the space between adjacent teeth on the corrugatedplate t and bear against the sides oil? the teeth to securely hold thebar against lateral movement; the material of which the bars are termedallowing the sides of the bar to be compressml slightly at their endswhen introduced into the serrated plate, so that the sides of the barwill hen against the sides of the teeth under tension to :lrictionallyengage the latter.

l orn'ied on the outer ends of the bars 5, are downwardly turned hookedmembers (3, as shown in Fig. 3, which are adapted to engage the endflanges 3 to tie the bars thereto and prevent the flanges fromspreading. \Vhere the plate A is sulliciently narrow the end bars 5 maybe formed without the hooks (i.

From the ;l,oregoing it will be seen that the space inclosed by theflanges 2 and 3 may be divided into as many compartments as may bedesired, by means oil the bars 5, and that any width of compartment maybe termed as occasion requires; the bars 5 being removable andinsertible in such ol the opposed serrations t as desired, to formspaces corresponding to the widths of the molding stamps.

The side flanges 2 are provided with slots 7 which extend the full.length ol the flanges 9. adjacent the bottom or plate A. The purpose ofthe slots 7 is to admit of such dust and dirt as may collect on theplate A being readily removed by the introduction through the slots 7oil' a current of air or a suitable wiping instrument. The plate A maythus be kept clean, thereby n'eventing the stamps from becoming cloggedby com tact with dust and dirt on the plate A when standing in the rack.

llaving thus described my invention, what I claim and desire to secureby Letters Patout, is

1. In a molding stamp 'ack the combination with a rectangular -framehaving corrugated plates mounted on the inner faces of its ends, oipartition bars Li -shaped in cross section, convergent end portionsadapted to extend between the corrugations on the frame to form a stableconnection between the ends of the bar and the frame, and downwardlyhooked members on the convergent ends of the bar adapted to project overand engage the ends of the frame to tie the bars and frame together andprevent spreading of the frame.

2. In a molding stamp rack, the combination with a rectangular framehaving toothed racks mounted on the inner faces of its ends, of amovable partition bar U- shaped in cross section, the vertical sideportions of the bar converging toward each other at the terminations ofthe bar and adapted to be inserted between the teeth of the rack withthe outer faces of the convergent portions of the bar bearing againstthe side faces of adjacent teeth in frictional engagement therewith, theupper portion of the bar extending beyond the convergent end portionsthereof and bent downwardly to form a hook member adapted to engage theends of the frame to prevent the toothed racks being spread out ofengagement with the ends of the bar.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Copies of this patent may be obtained for five cents each,by addressing the Commissioner of Patents,
